Review on 🔧 1108 Late Model GM Master Cylinder Adapter - Motive Products by Daniel Delgado

Works to bleed the brakes. Works much better than the two person pedal method. The problem is in the pressure. If you apply more than 10 pounds of pressure, the master cylinder will rupture. That's bad, because for some cars like GM, the factory manual calls for 35psi to bleed off the pressure. Cannot even exceed 10 PSI. I want to be able to get at least 20psi. If I were to buy this product again I would get a metal cap.
